Well i went to readioshack today and bought a switch because my Router only has one Ethernet port and that for my PC internet. So it finnaly figure out how to set it all up and i get on my xbox and its fine. I go over to my computer to activate my Xbox live card, but my internet isnt conencted. I check all the connections and their fine. My dad comes over and does something and now my internet is working but my Xbox live isnt getting a ip adress. So i try manually adding it and doest work. It says that maybe my Router is filtering out my consoles MAC adress. thats my problem. ow do i unfilter my XB360's MAC adress? Ny router is a Motorola SBV5220. My switch is a Netgear 5 port ethernet switch.
